Product Introduction
The LTC1666/LTC1667/LTC1668 are 12- /14- /16- bit, 50Msps differential current output DACs implemented on a high performance BiCMOS process with laser trimmed, thin- film resistors. The combination of a novel current- steering architecture and a high performance process produces DACs with exceptional AC and DC performance. The LTC1668 is the first 16- bit DAC in the marketplace to exhibit an SFDR (spurious free dynamic range) of 87dB for an output signal frequency of 1MHz.
Operating from ±5V supplies, the LTC1666/LTC1667/ LTC1668 can be configured to provide full- scale output currents up to 10mA. The differential current outputs of the DACs allow single- ended or true differential operation. The - 1V to 1V output compliance of the LTC1666/ LTC1667/LTC1668 allows the outputs to be connected directly to external resistors to produce a differential output voltage without degrading the converter's linearity. Alternatively, the outputs can be connected to the summing junction of a high speed operational amplifier, or to a transformer.
The LTC1666/LTC1667/LTC1668 are pin compatible and are available in a 28- pin SSOP and are fully specified over the industrial temperature range.
